Equipment Sales

At Precision Welding Supply, we offer reliable, high-quality equipment as well as services. We’re an orbital welding equipment distributor, purchasing and selling new and pre-owned products from brands like Tri Tool Inc. and MK Products. Reach out to our team or review our site for information on our current inventory or assistance in finding the ideal equipment for your operation.


We also have pre-sharpened tungsten electrodes available for purchase, with varying options for materials, diameters, lengths, angles, and finishes. Unlike user-ground electrodes, ours decrease variability when producing welds, allowing for greater stability, consistency in arc-starting, and increased electrode lifespan. Also, to ensure a high-quality product, we precision-grind tungsten for our electrodes utilizing best-in-class equipment, followed by microscopic inspections to verify consistency.

Calibration Services

Precision Welding Supply offers fast, cost-effective calibration services to verify the performance of your orbital welding equipment and minimize downtime in your operation. Calibrating your equipment is a proactive way to identify potential issues like rust, damage, or premature part failure and support high-quality, consistent welds. We certify our own equipment each year per the requirements of the National Institute of Standards and Technology (NIST).
